To all whom it may concern:

Be it known that I, SYDNEY H. PUDNEY, a subject of the King of GreatBritain, re-

siding at Toronto, in the Province of Ontario and Dominion of Canada,have invented new and useful Improvements in Smoke-Consumers andFuel-Economizers, of which the following is a specification.

This invention has relation to smoke consuming devices and has for itsobject the provision of a regulator to be fitted to the door openingleading into the combustion chamber of a locomotive or steam boilerfurnace, whereby the smoke and evolved gases resulting from combustionmay be consumed, thereby preventing the giving off of free carbon orsmoke.

The invention consists of a plate ar-.

ranged in the door opening of the fuel chamber and hinged so as to swinginwardly at its lower edge, said plate being controlled in its movementsby means of a motor consisting of a cylinder and a piston arranged tooperate Within the cylinder and having connection with a pipe, saidcylinder being adapted to be supplied with steam, compressed air, orother motive medium.

The invention consists of the novel features, details of constructionand combination of parts, which hereinafter will be more particularlyset forth, illustrated in the accompanying drawing, and pointed out inthe appended claim.

Referring to the drawing, forming a part of the specification.

Figure 1 is a sectional view of the combustion chamber of a locomotiveor steam boiler furnace provided with a smoke consuming or draftregulating mechanism embodying the invention.

Fig. 2 is a front view.

Corresponding and like parts are referred to in the followingdescription, and indi cated in all theviews of the drawing, by the samereference characters.

The numeral 1 designates the combustion chamber of a locomotive or othertype of steam boiler furnace, the same being provided with a dooropening 2 by means of which fuel is supplied to take the place of that.consumed. In accordance with this invention an annulus 3 is located inline with the door opening 2 and is secured to the furnace in anymanner. A door 4: closes the outer end of the extension 3. A plate 5 ismounted to swing inward at its lower edge.

A bracket 6 or like support is secured to the upper side of theextension or part surrounding the door opening 2 and the plate 5 ishinged thereto in any manner. The plate 5 extends across the spaceformed between the vertical sides of the door opening 2, but its lowerend terminates a short distance from the lower side of the door openingso as not to completely shut off draft when the door A is open. Byarranging the plate 5 so as to swing inward at its lower edge the airpassing into the furnace through the door opening is directed upon thebed of fuel and commingles with the gases and promotes combustion tosuch an extent as to prevent the giving off of any free carbon or smoke.

A motor is conveniently located exterior to the furnace and hasconnection with the plate 5 to control the, movements thereof. Thismotor consists of a cylinder 7 in which a piston is arranged to operate,said piston having its rod 8 connected with the plate 5 to control themovements thereof. Motive medium is supplied to the cylinder 7 by meansof a pipe 9, which may connect with the steam boiler or with acompressed air reservoir, the pipe 9 having a valve 10 which is adaptedto be controlled by means of a treadle 11 by pressure of the footthereon. When the door 4 is thrown open air enters the door opening andis deflected downward by means of the plate 5 so as to sweep over thefire and commingle with and "result in a perfect combustion of the smokeand gases. The plate 5 acts as a deflector and also as a damper andregulates the amount of air admitted into the furnace and causes theeiame to pass directly over the bed of the From the foregoingdescription, taken in connection with the accompanying drawing, theadvantages of the construction and of the method of operation will bereadily apparent to those skilled in the art to which the inventionappertains, andwhile I have described the principle of operation of theinvention, together with the device which I now consider to be the bestembodiment thereof, I desire to have it understood that the device shownis merely illustrative, and that such changes may be made when desiredas are within the scope of the claim appended hereto.

Hai ing thus described the invention What is claimed as new, is 4 p In adevice as described in combination a combustion chaiiiber,a reducedll'olliitw'e'xtension having a door opening into said combustionchamber, a removable hollo'W "door support fitted horizontally upon saidex- "tension and projecting 'therebeyond, a dependentbracket formed and'carriedby said door support and disposed snugly against itlieiupper'end of said eXt'efision'an'clat right "anglesthereto; a hinged pl'atemounted upon W'ardI-y "of the outer. end of said door sup- "'stippoit'ancl tnean's independent of said lid,

controlling said crank and adapted to cause 'saidp'lateto occupy angularpositions with 20 respect to said bracket. V
